SPECIFICATIO1\T formingpart of Letters Patent No. 234,758, dated November 23, 1880. Application filed April 30, 1880. (No model.)

To all whom tt may concern:

Be it known that I, POLYDORE DORGEVAL, of Paterson, in the county of Passaic and State ofNew Jersey, have invented a new and useful Improvement in Power-Looms; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of my invention is to fit looms for being driven by power for weaving classes of goods heretofore woven on hand-looms, and to provide an automatic device for tightening the filling at the end of the pick.

My invention consists First, in a lay or batten constructed in two portions, one portion consisting of the shuttlerail supported on arms that are vibrated by power, the other portion consisting of the reed carried by side arms hung on a shaft, which arms are moved to beat up by a weight. The reed-frame is behind the shuttle-rail, so that the backward movement of the reed is given by contact of the shuttle-rail.

Second, in a cam-and-link connection of peculiarconstruction for vibrating the batten and resting the same to give time for the passage of the shuttle.

Third, in fingers pivoted on the shuttle-rail and connected with slide-blocks in the shuttleboxes, for movement by the shuttle to raise and hold the weft-thread taut during the movement of the batten.

Fourth, in a brake operated by an arm on the shuttle-rail, for stopping the loom in case the shuttle stops short of its box.

These features will be more particularly described hereinafter, with reference to the accompanying drawings, forming part of this specification, wherein- Figure l is a side elevation of my improved loom, the heddles and warp-beam and their operating mechanism being omitted. Fig. 2 is a vertical transverse section. Fig. 3 is a vertical longitudinal section on lineyyof Fig. 2. Fig. 4 is a plan view, showing the cloth-beam and finishing-roll, the breast-beam being removed. Figs. 5 and 6 are side elevations of the frame of a loom, showing such parts only of the machine as are required to illustrate the operation of a portion of the brake and stop mechanism. Fig. 7 is a detail, in elevation, of a portion of the said brake and stop mechanism;

Fig. 8, a detail plan View, showing the operation of the device for holding the weft-thread taut during the movement of the batten; and Fig. 9 is a perspective view of aportion of the brake and stop mechanism with a portion of the frame shown broken away.

A is the frame of the loom; a, the breastbeam; and b the cloth beam or roller. 0 1s a shaft fitted in suitable bearings beneath the beam, and carrying at its end the pulleys d that operate the lay, as hereinafter descrlbed. This shaft 0 may be driven by hand or by a belt, 0, that passes around a pulley, 0 on the shaft 0, and a pulley, at, upon a driving-shaft, aflsecured by hearings to the lower and rear part of the frame.

0 is a shaft fitted in suitable bearings at the back and lower part of frame A. Upon this shaft, near its outer ends, are fitted the arms or swords ff, that carry the shuttle-rail g and boxes B, and also the arms h h, that are loose on the shaft and carry the reed-bars M, 111 which the dents of the reed are secured by any desired means. From the the hubs of the arms h on shaft 0 extend weighted arms k, which tend to throw the arms h and reed forward and maintain contact between the lower reed-bars, z, and shuttle-rail g.

From the arms f rodsl I extend forward and are connected to the slotted cam-pieces m,

which are hung at opposite ends of the loom by the arms 'It a, that are pivoted at the lower part of frame A. Upon the pulleys d are crank-pins d! which enter the slotted cams m. The slots of the cams m extend above and be low the center of pulleys d, so that by the revolution of the pulleys d the cam-pieces an and arms f are vibrated back and forth.

The slots of the arms on are so shaped as to operate the batten as follows: first, to cause the recoil of the batten with a medium rapidity; second, at the end of the course to give a deadpoint or rest to permit the shuttle to pass, and third, to cause the return movement to be made with great rapidity to permit the reed to be carried against the 'felljor edges of the cloth being woven with proper force by the action of the weighted arms. The shape of the slots on may be particularly described as having a concentric central portion and an. outwardlycurved or tangential end portion. By this construction the shuttle-race is moved forward by the power, and is followed up by the reed by the action of the weighted arms 70, and both the shuttle-rail and reed are moved back by power. The reed thus heats up the filling with a light stroke, which maybe regulated by ad justment of the weights is on arms 7c by means of set-screws k whereby the weights k may be secured at any desired position upon the arms to increase or decrease the effect of their weight. At the backward movement the shut-- tie-rail and reed-bars are in contact, and the shuttle will be thrown by any usual means at the pause in the movement.

The shaft 0, as shown in Figs. 3 and 4, is fitted with a spiral blade, 0. The cloth in passing from the beam at to the roller 0 passes at the back of roller 0 in contact with the blade 0, and by the revolution of shaft 0 the blade is caused to rub upon the face of the cloth to smooth and finish the surface.

Upon the front of the shuttle-rail g, at each end, a finger, 0, is pivoted, from which finger a rod, 19, extends to and is connected with a lever, q, that is hung on the front of rail g. The upper end of lever q is bent back above the shuttle-box B, as shown in Fig. 1. In the box B is fitted a loose slide-block, r, and connected with the lower end of lever q is a spring, q, that tends to throw the finger 0 down be low the upper edge ofthe rail g. As the shuttle enters the box it strikes the block 1", moves it back, and thus moves the lever q and raises the finger 0. The finger 0 in this position will come in contact with the weft as the reed moves forward, taking up the slack in advance of the reed and holding the weft taut until the shed has changed, after which, the shuttle beingshot and the block 1" thus relieved, the spring 9 will instantly carry the fingers 0 down out of the way ot'the shuttle. The finger 0 rises after the shuttle has passed and entered its box, and then as the lay goes forward the finger passes upon the filling-thread and carries the thread forward. This takes up the slack, and the thread is held tightly as the reed beats up, thereby insuring a tight selvage.

The blocks r are also used to throw the stopmotion out of action when the shuttles enter the boxes, and allow the same to act if the -.$h rttles fail to enter. A lever, s, hung beneath each box, B, is connected by one end to block 1", and carries at the other end a rod, t, that slides in a lug or flange on the rod Z of the "ibrating arm f. Between the arms f, and pivoted in said arms, is a cross bar or red, it, having projections a, Fig. l, which extend toward the arms '1) of the brakes '0, that are pivoted at v on frame A, to bear on the periphery of the pulleys d. The rod to also carries arms 20, which are above the slide-rods t. At the forward movement of arms f the projections to will come in contact with the brakearms to brake the pulleys except when the rod to is moved or held by the rods t passing beneath the arms 20, as shown in Fig. 7. This forward movement of rods tis accomplished by contact of the shuttle with block 1 as the shuttle enters the box, so that as the lay goes forward the swinging movement of the rods Z will raise the rods t and arms to, and the projections w will pass above the brakearms without effect. The rod to and its arms and projections are restored to their operative positions after the rod 25 is withdrawn by the weight of the said arms and projec tions, which are all arranged upon the same side of its axis, and the strength of the spring t issufficient to hold the rod if out of action.

It will thus appear that the projections a are held up by rods t at each end of the lay acting alternately upon the arms w of the shaft to. The rods t are withdrawn as the shuttle is thrown by the spiral springs t.

The brakearms 'u will be connected to suitable devices for throwing off the power at the same time the brake is applied, and it will be seen that in case the shuttle fails to enter the box the stop-motion will remain operative.

The mechanism for throwing off the power at the same time the brake is applied is as follows: a a are the loose and fast pulleys on the driving-shaft a 1) is the belt-shifter, fitted on frame A, to which is also fitted the crossshaft 0, that extends from the front to the back of said frame, and has an arm, 0, at the back that connects with the belt-shifter b, and a crank-arm, 0 at the front that connects with the spring-lever f. The spring of lever f tends to move the belt-shifter and throw the belt on the loose pulley. The upper end of the lever f passes through a guide, 9, having an L-slot, on which guide is pivoted a lever, h. One arm of said lever h is connected to the brake-arm o by rod 7L2, while the other extends at the side of lever f. The lever f is moved by hand to shift the belt to fast pulley, and then caught upon the shoulder g of the L-slot to prevent its return. The movement of brake-arm o to brake-wheel d, as before described, causes lever h to disconnect lever f from the shoulder g by pressing against it, so that the spring of the latter is free to act. The rod to is provided with projections to on both sides of the loom for operating the brakearms U, so that the stop-motion is brought into action from either side of the loom.

By the construction described the loom is adapted for weaving by power any kind of rich or common goods. In weaving common goods, such as are usually woven by power,

IIS

the two-part batten may be connected together I by suitable fastenings.

Having thus described my invention, what I claim as new is 1. In looms for weaving, the double lay or batten, consisting of the arms f, and shaft 0, the shuttlerail 9 carried thereby, the drivingshaft provided with positive connections with the rail, in combination with the arms h, pivoted to the shaft 0, independently of arms f, the weighted arms, and the reed secured to the arms h, and operated upon to receive the backward movement by the pressure of the shuttle-rail and its forward movement by the Weights, substantially as described.

2. In combination with the pivoted arms f and shuttle-rail g and vibrating arms h, carrying the reed, the rods 1, slotted and pivoted cam-pieces m, pulleys d, provided with pins 01, and driving-shaft c, for vibrating the arms f, these parts being constructed, combined, and

arranged to operate substantially as specified. 3. In looms for Weaving, the pivoted fingers 0, rods 12, levers q, and slide-blocks 1", combined
